CHARLES S. BEEBE, OF RAOINE, VVISOONSIN.

FANNlNG-MILL.

SPECIFICATION forming part of Letters Patent No. 280,898, dated July 10,- 1883.

Application filed May ,26, 1883. (No model.)

To all whom, it-may concern:

Be it known that I, CHARLES S. BEEBE, of

' Racine, in the county of Racine, and in the State of IVisconsin, h. ve invented certain new and useful Improvements in Fanning-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to fanning-mills; and it consists in certain improved mechanism wherewith the shoe that carries the screen is supported and shaken, as will be fully described hereinafter.

In the drawings, Figure 1 is a perspective view of a machine embodying my invention with a part of the top thereof broken away, and Fig. 2 is a side view.

The main object of my invention is to pro vide in one machine mechanism for hanging the shoe so that it can be adjusted to shake bodily from side to side, or to oscillate on an arc of a circle. The former is styled in the trade the body shake, and the latter the flirt shake; and hence in this application I show and describe the devices for producing both the body and flirt shake, because all my machines are made to embody both and to change from one to the other; but as I have already filed an application on the 7th day of December, 1881, wherein I have claimed the mechanism for producing the body shake, I claim in the present application only the construction requisite for the production of the flirt shake.

a rod. E. A bar, G, is fastened to the shoe A at its front end and midway between its sides, and the front end'of this bar projects forward and up against the top of the casing A and into a staple, H, which is provided with a groove, I, and the ends of which staple are screw-threaded and project up through the top of the casing to receive set-nuts F F. To

give the shoe the body shake, set-nuts F F are loosened to allow the staple H to drop down away from the top of the casing, as shown in Fig.1. This leaves bar G free to. slide from one end to the other of the staple H. The hangers B are then caught over lugs J and hangers K in lugs f. The shoe will now be supported evenly on each side of the elbowplate 0, and, as it is connected with the fanwheel crank by elbow-lever D and rod E, each revolution of the crank will throw the shoe from one side to the other of the casing and back again, and in these reciprocations the front and rear of the shoe will both travel together at rightangles to'the length of the easing. Now, to change the shake from body to the flirt, hangers B are withdrawn from the lugs J, so as to let the weight of the body of the shoe rest entirely upon the hangers K and bar G, and the staple H is tightened up against the casing, as shown in Fig. 2, so as to confine the end of bar G in groove I, which groove, while it is sufficiently large to permit,

the bar to oscillate in it, will hold it against lateral play. Therefore, if the fan-wheel be turned, it will cause the rear of the shoe to vibrate in the are of a circle of. which a vertical line drawn throughthe groove I of the staple H is the center, and thus will be produced the flirt shake.

The hangers B, I have shown swivcled in i11- clined bearings in the lugs c d, attached to the top and sides of the frame of the mill. The hangers K are suspended from lugs b, secured to the rear end of the frame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, in a fanning-mill, of the casing, screen-shoe, bar G, adjustable staple H I F, hangers K, lugs f and 11, plate 0, bellcrank lever D, and'crankrod E, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, on this 4th day of May, 1883, in the presence of two witnesses.
